Pull networking fixes from David Miller: "Lots of bug fixes here: 1) Out of bounds access in __bpf_skc_lookup, from Lorenz Bauer. 2) Fix rate reporting in cfg80211_calculate_bitrate_he(), from John Crispin. 3) Use after free in psock backlog workqueue, from John Fastabend. 4) Fix source port matching in fdb peer flow rule of mlx5, from Raed Salem. 5) Use atomic_inc_not_zero() in fl6_sock_lookup(), from Eric Dumazet. 6) Network header needs to be set for packet redirect in nfp, from John Hurley. 7) Fix udp zerocopy refcnt, from Willem de Bruijn. 8) Don't assume linear buffers in vxlan and geneve error handlers, from Stefano Brivio. 9) Fix TOS matching in mlxsw, from Jiri Pirko. 10) More SCTP cookie memory leak fixes, from Neil Horman. 11) Fix VLAN filtering in rtl8366, from Linus Walluij. 12) Various TCP SACK payload size and fragmentation memory limit fixes from Eric Dumazet. 13) Use after free in pneigh_get_next(), also from Eric Dumazet. 14) LAPB control block leak fix from Jeremy Sowden" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (145 commits) lapb: fixed leak of control-blocks. tipc: purge deferredq list for each grp member in tipc_group_delete ax25: fix inconsistent lock state in ax25_destroy_timer neigh: fix use-after-free read in pneigh_get_next tcp: fix compile error if !CONFIG_SYSCTL hv_sock: Suppress bogus "may be used uninitialized" warnings be2net: Fix number of Rx queues used for flow hashing net: handle 802.1P vlan 0 packets properly tcp: enforce tcp_min_snd_mss in tcp_mtu_probing() tcp: add tcp_min_snd_mss sysctl tcp: tcp_fragment() should apply sane memory limits tcp: limit payload size of sacked skbs Revert "net: phylink: set the autoneg state in phylink_phy_change" bpf: fix nested bpf tracepoints with per-cpu data bpf: Fix out of bounds memory access in bpf_sk_storage vsock/virtio: set SOCK_DONE on peer shutdown net: dsa: rtl8366: Fix up VLAN filtering net: phylink: set the autoneg state in phylink_phy_change net: add high_order_alloc_disable sysctl/static key tcp: add tcp_tx_skb_cache sysctl ...
